openssl: only allow ephemeral RSA keys in export ciphersuites (FREAK)

It was discovered that OpenSSL would accept ephemeral RSA keys when using non-export RSA cipher suites. A malicious server could make a TLS/SSL client using OpenSSL use a weaker key exchange method...

The vulnerability of the OpenSSL library, which allows a hacker to trigger a service failure

The vulnerability in the ssl/s3clnt.c function of the OpenSSL library arises due to synchronization errors when using a shared resource. Exploiting this vulnerability allows a malicious actor to trigger a service denial game-of-thrones behavior and subsequent release by using a specially created...

TLS 1.2 Transcipt Collision attacks against MD5 in key exchange protocol (SLOTH)

A flaw was found in the way TLS 1.2 could use the MD5 hash function for signing ServerKeyExchange and Client Authentication packets during a TLS handshake. A man-in-the-middle attacker able to force a TLS connection to use the MD5 hash function could use this flaw to conduct collision attacks to...

Google Testing Post-Quantum Cryptography in Chrome

Plenty has been speculated since the Snowden documents were made public about the NSA’s interest in building a quantum computer that could break current encryption securing communication worldwide. Quantum computing on a practical scale is a distant goal, but some do exist that leverage some...

The vulnerability of the Java Platform software platform allows a malicious actor to simplify the process of decoding messages remotely.

A vulnerability in the Java Platform software framework, related to a bug in the ssl3getkeyexchange function in the s3clnt.c file of the OpenSSL cryptographic library. Exploiting this vulnerability could allow an attacker to simplify the decryption process by using an insufficiently secure RSA ke...

The vulnerability of the Java Platform software platform allows a remote attacker to compromise the confidentiality and integrity of protected information.

The vulnerability of the Java SE software platform allows a malicious actor to compromise data confidentiality and integrity by exploiting the Diffie-Hellman algorithm for key exchange...

Vulnerability of Cisco IOS software, which allows a malicious actor to trigger a service failure

The vulnerability in Cisco IOS and IOS XE allows malicious actors operating remotely to trigger a service failure device reboot through improperly generated IKEv2 packets...

The vulnerability of the Cisco IOS operating system, which allows a malicious actor to trigger a service failure

Cisco IOS software contains a vulnerability in the Internet Key Exchange IKE protocol. This vulnerability allows a malicious attacker to send specially crafted IKE packets to any of the UDP ports 500, 848, 4500, or 4848. This causes the router to restart and trigger a “service failure”...

GLSA-201606-12 : libssh and libssh2: Multiple vulnerabilities

The remote host is affected by the vulnerability described in GLSA-201606-12 libssh and libssh2: Multiple vulnerabilities libssh and libssh2 both have a bits/bytes confusion bug and generate an abnormaly short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange...

Libreswan IKEv1 Protocol Denial of Service Vulnerability

Libreswan is an Openswan-like implementation of IPsec developed by software developer Paul Wouters, which is used to ensure security and integrity issues in data transmission. A denial of service vulnerability exists in the IKEv1 protocol in Libreswan version 3.16. An attacker is allowed to explo...

Symantec Veritas NetBackup and NetBackup Appliance Weak Key Exchange Vulnerability

Symantec Veritas NetBackup NBU and NetBackup NBU Appliance are both products of Symantec USA. The former is a set of enterprise-class backup management software that can run on multiple operating systems, and the latter is an enterprise-class backup management appliance. A security vulnerability...

CVE-2015-6551

Veritas NetBackup 7.x through 7.5.0.7 and 7.6.0.x through 7.6.0.4 and NetBackup Appliance through 2.5.4 and 2.6.0.x through 2.6.0.4 do not use TLS for administration-console traffic to the NBU server, which allows remote attackers to obtain sensitive information by sniffing the network for...

Code injection

Veritas NetBackup 7.x through 7.5.0.7 and 7.6.0.x through 7.6.0.4 and NetBackup Appliance through 2.5.4 and 2.6.0.x through 2.6.0.4 do not use TLS for administration-console traffic to the NBU server, which allows remote attackers to obtain sensitive information by sniffing the network for...

Cisco IOS Software Internet Key Exchange Version 2 Fragmentation Denial of Service Vulnerability (cisco-sa-20160323-ios-ikev2)

A vulnerability in the Internet Key Exchange IKE version 2 v2 fragmentation code of Cisco IOS Software could allow an unauthenticated, remote attacker to cause a reload of the affected system. SPDX-FileCopyrightText: 2016 Greenbone AG Some text descriptions might be excerpted from a referenced...

Analyzing TLS Libraries: TLS-Attacker

TLS-Attacker is a Java-based framework for analyzing TLS libraries. It is able to send arbitrary protocol messages in an arbitrary order to the TLS peer, and define their modifications using a provided interface. This gives the developer an opportunity to easily define a custom TLS protocol flow...

Libreswan Denial of Service Vulnerability (CNVD-2016-02380)

Libreswan is an Openswan-like implementation of IPsec developed by software developer Paul Wouters, which is used to ensure security and integrity issues in data transmission. A security vulnerability exists in Libreswan version 3.16. A remote attacker can exploit this vulnerability to cause a...

The vulnerability of the Cisco IOS operating system, which allows a intruder to trigger a service failure

The vulnerability of the IKEv2 operating system implementation of Cisco IOS is related to resource management errors. Exploiting this vulnerability allows a malicious actor to trigger a service failure device reboot by using fragmented packets...

Type confusion

libssh before 0.7.3 improperly truncates ephemeral secrets generated for the 1 diffie-hellman-group1 and 2 diffie-hellman-group14 key exchange methods to 128 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes...

UBUNTU-CVE-2016-0787

The diffiehellmansha256 function in kex.c in libssh2 before 1.7.0 improperly truncates secrets to 128 or 256 bits, which makes it easier for man-in-the-middle attackers to decrypt or intercept SSH sessions via unspecified vectors, aka a "bits/bytes confusion bug."...
